[Dovecot] Adding new password schemes?

Hi, all.

I was curious how difficult it would be to add a new password scheme to Dovecot? I have to transplant mailboxes from one machine to another, the older machine running Post.Office from now-defunct Software.Com, which was bought by OpenWave, then discontinued. Apparently, Netscape's mailserver offering from the day also supports this scheme. There's code out there that was incorporated into OpenLDAP a while back which can read this scheme, but I need to use MySQL as a source for this.

Thanks in advance for any help anyone can offer.
